NOTES:
•
Follow the local codes and regulations when selecting field wires.
•
Power cord selection shall not be lighter than IEC60245-1 provisions of the neoprene sheath cable
57 requirements, and the power cord should be copper wire.
•
Use a shielded cable for the transmitting circuit and connect shielding layer to the ground.
•
In the case that power cables are connected in series, add maximum current to each unit and select
wires as follow table.

WARNING
!
•
Tightly secure wirings to the terminal block according to the specified torque. If tightening the terminals
is not completed, heat generation, an electric shock or a fire will occur at the terminal connection.
•
Make sure that the wires are securely fixed in order not to apply an external force to the terminal
connection of the wirings. If fixing is not completed, heat generation or a fire will occur.
•
Make sure that the terminals do not touch the surface of the electrical box. If the terminals are too
close to the surface, it may cause the activation of ELB, heat generation and a fire at the terminal
connection, and an electrical shock.
1. The electrical wiring connection at the terminal block for the indoor unit is shown in the figure below.
Check the outdoor unit for the combination before starting the wiring work.

NOTES:
(1) Terminals TB2 is installed on the main board. Each connection hole can be connected to one or
2
two 0.75mm
transmission wires. Generally, each connection hole is connected to one wire, and is
connected to two wires only when the center controller is connected.
(2) Connect the control cables between the indoor unit and the outdoor unit correctly.
(3) Use the shielded twist pair cable for control between the outdoor unit and the indoor units. They
are connected to the terminals 1 and 2 of the terminal blocks(TB2) on the PCB. The Wired remote
controller cable is connected to the terminals A and B of terminal block (TB2) on the PCB.
(4) Check to ensure that the shielded twist pair cable(0.75mm
and size complying with local code are used for intermediate wiring between the outdoor unit and
the indoor units to prevent noise obstacle.
